Answer:

When two substances that are of different temperatures are brought together and there is heat transfer such that the substances come to thermal equilibrium, the effect on the particle motion are as follows

1) The particle motion of the hotter body reduces, because its temperature reduces

2) The particle motion of the colder body increases, because its temperature increases

3) For gases, the volume and or pressure reduces for the hotter body, and if the temperature of the gas falls below the boiling point temperature, the gas will change into liquid

For the colder gas, only the volume and or pressure increases and the temperature rises

4) For liquids, if the temperature of the hotter liquid falls below the melting point, the hotter liquid will become a frozen solid

For the the colder liquid, if the temperature is raised above the boiling point, the liquid changes into gas and the temperature does not rise above the boiling point temperature, until all the cold liquid has evaporated

5) For solids, the vibration of the particles of the hotter substance reduces and the solid becomes more brittle

For the colder body, the rise in temperature causes an increase in vibration of the particles, and if the temperature rises above the melting point, the colder solid will begin to melt

The density of an object = 5 g/ml

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

The unit of density can be expressed in g/cm³ or kg/m³  

Density formula:  

[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]

ρ = density  

m = mass  

v = volume  

Mass = 50 g

Volume of the object =

[tex]\tt 40-30=10~ml[/tex]

So the density :

[tex]\tt \rho=\dfrac{50}{10}\\\\\rho=\boxed{\bold{5~g/ml}}[/tex]

There don't appear to be any dial tone problems on the telephone caused by broken wires, connectors, wall jacks, or other network-interfering hardware.

Hardware describes the physical parts of the computer or its delivery mechanisms for the software's written instructions to be stored and executed. The device's intangible component that enables user interaction with the hardware is called the software.

Software is referred to as "soft" because it is flexible, but hardware is referred to as "hard" because it is rigid in terms of modifications. Software often instructs hardware to carry out any command.

Since a smartphone is fundamentally a small computer, it has several parts in common with computers, such as processors and memory. It's critical to balance your demands on this hardware because these components are continuously improved in new phone generations.

Thus, It doesn't seem that any broken wires, connectors, wall jacks, or other network-interfering gear are the root of any dial tone issues on the hardware.

3. One example of condensation is dew forming on grass or leaves early in the morning when the air is cooled/cooling.

4. This is called freezing. For example, when water turns into ice (a solid) because it freezes.

5. This is called melting. The butter reached its melting point and turned into a liquid.

6. Adding or removing energy causes changes in states of matter. Temperature for example can cause melting and freezing.

7. Water which collects as droplets on a cold surface when humid air is in contact with it.

8. Evaporation/vaporization

9. before- particles are compact

during- particles vibrate

after- the particles move freely

10. condensation because it is going from gas into a liquid

11. Evaporation, I know because when liquid gets heated after a period of time  and it reaches its boiling point, it will begin evaporating.

12. When a solid is heated the particles gain energy and start to vibrate faster and faster. ... Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid. The particles in the liquid are the same as in the solid but they have more energy.

13. Sublimation is the process of transformation directly from the solid phase to the gaseous phase, without passing through an intermediate liquid phase.

14. freezing because particles are becoming compact and getting slower because of decrease in temperature

15. Examples are mothballs, dry ice, snow in the winter months, freeze-drying (ice crystals in a frozen food bag), air fresheners, and printers that print out high-resolution images.

16. Try and think of it in terms of the molecules. The temperature is such that the molecules are all bound together into a solid. Occasionally a surface molecule picks up enough energy to break it bond,.. a statistical probability ,and drifts away. The overall temperature of the solid is reduced by that event,as temperature is just an average of the energy. A little more heat flows into the material ,from the ambient environment, and another molecule escapes, and so the process continues….. if the concentration of the molecules in the vapour space above the solid, is low the reverse process of molecules condensing onto the surface,and releasing energy back into the solid is low.

Ammonia consist of nitrogen and hydrogen.

Chemical equation:

N₂ + H₂    →   NH₃

Balance chemical  equation:

N₂ + 3H₂    →   2NH₃

We can see that nitrogen and hydrogen react with each other and from ammonia.

Nitrogen is present in group 5A.  The atomic number of nitrogen is 7.  Its atomic mass is 14 amu.  It has 5 valence electron.

Electronic configuration:

N₇ = 1s² 2s² 2p³

we can see there are five electron in outer most shell. Thus, nitrogen needs three more electrons to complete the octet.  When it combine with other atoms it gain three electron from them

While hydrogen is present in group 1A. It has one valence electron. In ammonia (NH₃) when nitrogen react with hydrogen it gain three electrons thus three atoms of hydrogen combine with one atom of ammonia because one hydrogen atom can share only one electron. Covalent bond is formed between nitrogen and hydrogen and new substance formed is called ammonia.

Explanation:

Answer:

increased, 7.5-8.3 atm; decreased, 3.5-4.3 atm; Gay-Lussac's Law

Explanation:

1. The collision of gas molecules, results in the pressure increases.

2. The pressure of the system with an increase in the temperature has been 7.2-8.2 atm.

3. The pressure of the system with a decrease in the temperature has been 3.6-4.1 atm.

4. The relationship between the molecules has been given by Gay-Lussac's Law.

The relationship between the temperature and pressure has been given in the gaseous molecules with the ideal gas equation.

1. The temperature has been directly proportional to the temperature. Thus, with an increase in pressure, there has been an increase in temperature and vice versa.

With the collision of the gas molecules with the wall, there has been the liberation of the energy that increases the temperature. The increase in temperature mediates the increase in pressure.

Thus, with the collision of gas molecules, the pressure increases.

2. The relationship between the pressure and temperature has been given as:

[tex]\dfrac{P1}{T1}=\dfrac{P2}{T2}[/tex]

The initial temperature [tex]T1=300\;\text K[/tex]

Final temperature [tex]T2=400\;\text K[/tex]

Initial pressure, [tex]P1=5.4-6.2\;\text {atm}[/tex]

Final pressure, [tex]P2[/tex]

Substituting the values for calculating P2 as:

[tex]\rm \dfrac{5.4-6.2\;atm}{300\;K}=\dfrac{P2}{400\;K}\\\\\textit P2 = \dfrac{5.4-6.2\;atm}{300\;K}\;\times\;400\;K\\\\\textit{P}2=7.2-8.2\;atm[/tex]

The pressure of the system with an increase in the temperature has been 7.2-8.2 atm.

3. The pressure with the reduction of temperature has been given by :

[tex]\dfrac{P1}{T1}=\dfrac{P2}{T2}[/tex]

The initial temperature [tex]T1=400\;\text K[/tex]

Final temperature [tex]T2=200\;\text K[/tex]

Initial pressure, [tex]P1=7.2-8.2\;\text {atm}[/tex]

Final pressure, [tex]P2[/tex]

Substituting the values for calculating P2 as:

[tex]\rm \dfrac{7.2-8.2\;atm}{400\;K}=\dfrac{P2}{200\;K}\\\\\textit P2 = \dfrac{7.2-8.2\;atm}{400\;K}\;\times\;200\;K\\\\\textit{P}2=3.6-4.1\;atm[/tex]

The pressure of the system with a decrease in the temperature has been 3.6-4.1 atm.

4. The relationship between the molecules has been given by Gay-Lussac's Law. The law states that pressure has been directly proportional to the absolute temperature of the system.

Answer:

The short steep ramp would be much harder because you will have to work more against gravity.

Explanation:

The long shallow ramp would be easier to take than the short, steep ramp because the person would have to use more force on the short, steep ramp to push the wheelchair against the force of gravity.

An inclined plane or a ramp can be defined as a flat supporting surface tilted at an angle, with one end higher than the other, utilized as an aid for raising or lowering a load.

The inclined plane can be defined as one of the six classical simple machines developed by Renaissance scientists. Inclined planes can be utilized to move heavy loads over vertical obstacles.

Moving a body up an inclined plane needs less force than lifting it straight up, at a cost of an increase in the distance moved. The mechanical advantage, the factor by which the force is decreased, is equal to the ratio of the sloped surface's length to the height it spans.

The inclined plane provides the same amount of work to be done with a smaller force exerted over a greater distance. The angle of friction or the angle of repose can be defined as the maximum angle at which a load can rest motionless on an inclined plane because of the friction without sliding down.

It contains more water vapor than cold air

According to the process of conduction which take place from hot to cold end warm saturated air has more water vapor than cold air.

Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.

In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .

As per the concept of conduction, warm hair has more water vapor than cold air, thus the correct option is that warm, saturated air has  more water vapor than cold air.
